MOTOR-VEHICLE.

Specification of Letters Patent.

Patented Jiily c.1920.

have invented certain new and useful Improvements in Motor vehicles, of which the following is a specification.

This invention relates to motor vehicles, and particularly to folding seats especially adapted for use therein.

One of the objects of this invention is to provide a folding seat having improved swinging mounting.

Another object of this invention is to provide a swivel folding seat having yielding means for limiting the swivel movement of the chair.

These and other objects will clearly appear from. the following description taken in connection with the accompanying drawings, which form a part ofthis specification, and in which:

Figure 1 illustrates a fragmentary view; with portions in section, of the interior of a motor vehicle embodying a preferred form of my invention; v

Fig. 2 is a transverse fragmentary View, with portions broken away, substantially on the line 2-2 of Figure 1;

Fig. 3 is a vertical section substantially on a line 3-3 of Fig. 2; and

Fig. 4 is a vertical section substantially on a line 4-4 of Fig. 2; and

Fig. 5 is a vertical section substantially on a line 5-5 of Fig. 2.

Referring to the drawings, 10 illustrates one of a pair of frame side members on which may jbe suitably mounted a vehicle body, the forward construction of which is indicated as 11. The floor board 12, and an inclined foot board 13, are formed with a recess 14, in which a folding seat, more particularly hereinafter, is adapted to be arranged when in folded position. A pan 15, having struck-up flanges 15, is arranged in the recess.

Suitably formed, or otherwise secured to the flanges 15, are bosses 17, having vertically arranged slotted portions 18. A base,

or transverse member 19, is provided with trunnions 20, which are adapted to be inserted through the slotted portions 18 of the bosses 17, and to be rotatably mounted therein.

The base member 19,. is formed with a boss 20, having at its upper end a cam surface or offset portion 21. A vertical trunnion 22, 1s adapted to be supported in the boss 20. A chair comprising a supporting frame 23, a seat member 24, and a back member 25, is adapted to have a swivel mounting, as will be presently described, on the trunnion 22.

It will be noted that the seat member 24, is pivoted as at 26, adjacent its forward end to the supporting frame 23, and that the back member 25 is pivoted as at 27, to the back of the seat member 24. The bottom member 28, of the seat frame 23, is formed Wltlllf boss29, which is adapted to be mounted on the trunnion 22. It will be noted that-the bottom part of the boss 29,

is formed with a cam surface 30, comple igisentary to the cam surface 21 of the boss After the seat frame 23 is mounted in position, a spring 31 is arranged between the top of the boss 29, and a nut 32, suitably secured to the upper end of the trunnion 22; It will be noted that with the parts in the described relation, the offset portions of the cam surface 30 on the boss 29, will abut against similar complementary por-' tions of the cam surface 21 of the boss 20. Therefore, the supporting member 23 of the chair, may be swung on its vertical pivot 22 only after the spring 31 has been compressed, permitting the inclined faces of the cam 30 to ride upwardly on thecomplementary faces of'the cam surface 21. Of course, when the chair is in the position illustrated in Figure l, the spring 31 will normallymay then be swung on its trunnions 20 untilthe sides 35 of thetrunnions 20, are alined with the slotted portions 18 of the bosses 17 at which point the seat may be entirely disconnected fromthe body by merely lift- I ing it upwardly. However, if it is desired extendin to maintain the seat in its mounting, the operator will continue to swing the supporting frame 23, forward on its trunnions 20, until the back of the supporting frame is flush with the floor board 12, and then the seat member 24 will be swung forward on its pivot 26 until its back is flush with the inclined foot board 13.

It will be understood that the main purpose in providing the swivel mounting of the chair on its base, is to facilitate getting into and out of the chair.

I am aware that it has been known to arrange a folding seat on metal supports or irons which were folded into slots in the floor of a vehicle and I do not broadly claim the same, but do claim as broadl novel the arrangement of a section of the oor proper whereby it may be made to form a seat support or section and be ralsed to expose. a

well or recess whereby, when the seat is.

ready for occupancy, increased space will have been made in the floor or other parts of the vehicle immediately in front of the seat to better accommodate the limbs'of a person occupying the seat.

While I' have described and will specifically claim what I deemto be a preferred embodiment of my invention, it will, of course, be obvious to those skilled in the art, that various modifications and changes may be made without departing from the spirit and scope hereof.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: v

-. 1. In a device of the class described and in combination with a vehicle body, two bosses spaced apart from one another and supported from said body; a transversely base member pivotally supported in said bosses and capable of oscillating movement therein; means for limiting the extent of movement of said transverse base in one direction; a vertically extending trunnion carried by said base; a frame having a bottom member supported by and rotatable about said-trunnion; a chair seat carried by said frame; cooperating cam members upon said base and the bottom member of said frame and whereby said base and frame are maintained in definite relation relative to-one another; and a spring acting to hold said members in engagement with one another.

2. In a device of the class described and in combination with a vehicle body, two

' bosses supported from said body and spaced apart from one another; a base pivotally supported in bearings provided in said bosses; means for detachably holding the free ends of said'base in position relative to said bosses so that said base member may oscillate about a horizontal axis and at the same time may be readily removed from supported by said body and spaced apart from one another; a transversely extending base member pivotally supported by and removable from said bosses byupward movement imparted to said base; an upwardly extending frame pivotally connected with said base and rotatable about a vertical axis when the device is in use; a chair seat pivotally;

connected with the upper end of said frame;

and means for limiting the movement of said base in one direction to thereby position said seat properly so that the same may be occupied.

4. In a vehicle body, a transverse member having a horizontal'pivotal mounting therein, a chair having a vertical pivotal connec tion thereon, said connection comprising a cam and spring device adapted to normally hold said chair in a definite position and to yield to permit said chair to be rotated about avertical axis, said chair comprising a supporting frame adapted to form a floor board in folded position, a seat member pivoted thereto, and a back pivoted to said seat member.

5. In a vehicle body, a pair of oppositely disposed slotted bosses, a transverse member having trunnions mounted in said bosses,a boss" arranged on said transverse member, said boss having a cam on its upper end, a

I chairframe adapted to form a floor board in folfded position and provided with a boss having a cam at its lower end, and means for pivotally connecting said bosses comprising a spring.

' 6. In a vehicle body, a pair of slotted bosses, a transverse member having flattened trunnions mounted in said bosses, a boss arranged on said transverse member, said boss having a cam on its upper end, a chair frame adaptedto form a floor board in folded position and provided with a boss having a cam at its lower end, means for pivotally connecting said bosses comprising a spring, a seat member pivotally connected with said frame, and a back member pivotally connected with said seat member.

7. In a vehicle body, a pair of bosses spaced apart from one another, a transverse member having trunnions horizontally mounted therein and removable from said bosses, a supporting member adapted to form a floor board in folded position and pivotally mounted on said transverse member, means for limiting the relative pivotal movements of said members, a seat member pivotally connected with said supporting member, and a back member pivotally connected with said seat member.

8. In 'a vehicle body, a pair of bosses spaced apart from one another, a transverse member having trunnions mounted therein and removable from said bosses in a vertical direction, a supporting frame adapted to form a floor board in folded position and having a pivotal mounting on said transverse member, the axis of said pivotal mounting and said trunnions being in transverse relation, means for yieldingly limiting the pivotal movement of said supporting member on said transverse member, a seat member pivotally mountedon said supporting member, and a back member pivotally mounted on said seat member.

9. In combination, a vehicle body having a floor board and a foot board inclined relatively thereto, said boards having a recess formed therein, a base member having trunnions horizontally mounted in said floor board, a chair pivotally mounted on said base member, said chair comprising a supporting member adapted to form a floor board in folded position, a seat member pivotally connected thereto, aback member pivotally mounted on said seat member, said back member being adapted to be folded ed to be swung relative to said supporting member whereby the back of said supporting member and the backof said seat member will be substantially fiusld with said floor board, and said foot board, respectively, when said chair is folded. 10. In a vehicle body having a floor board and a foot board inclined relatively thereto, a chair provided with a supporting member adapted to form a floor board in folded position and having trunnions horizontally mounted in said floor board, a seat member pivotally connected with said supporting member, said foot board and said floor board having a recess formed in them, said supporting member being adapted to be swung on its trunnions, and said seat member being adapted to be swung on its pivotal connection whereby the back of said supporting member and the back of said seat member will be substantially flush with said floor board and said inclined foot board, respectively, when saidchair is in folded position. In testimony whereof l affix my si nature.
